I think that was the original intention, but Ive only ever bouldered them. Im sure slapping the lip is sufficient to claim a send on most, its just a mantle move youre leaving out, not exactly a hard move!

The fact is, if there are no top anchors, top-out is the only acceptable way of finishing the route. Faberge (in Fernkloof) used to be like that, but anchors were only added later on. It follows then that grabbing the lip is not sufficient - when one boulders it is very rare not to top out, and if the top-out is really as easy as Xmod says it is, why not just go through the very little extra effort and top out? It'll spare a debate.

Topping out would be the ethically pure way to finish for sure, especially if boudering. On that part of the Mine this then entails walking all the way rightwards to the end of the ledge downclimbing and walking back. I guess Ive always viewed visits to the Mine as just training and - Im lazy!

Now to shake off this extended lazy spell and actually get fit enough to visit the Mine again! But thats another story. Psyched to climb again!
